The vertical sideofthegangle bracket is drilled forgthe Ireception of a pivot-bolt 29 onwhich an arm 31 of a pipe bending die member havimgHai-.head 32ispivotally mounted. From the foregoing it will be appreciated that thearm 27 may beswungabout .the pivot provided bythe bolt 25 in one planeand that the die member .may be swung about both the pivot 2 5. and thepivot 29 so-that it may have substantially .universal movement withrespect -tothe base. i

L. arm 27 isprovided with upst-anding lug portions 334 and 34 providingbetween them a necess 35 adapted toreceive a pipe or the like 'and'therecess 35 is arranged so that when vth e,arm.27 is in the position shownin Figs. 2 and .3;'it will align` withthe opening between -the jaws ofthe vise. This arrangementisa decided aidin securing the pipe 36 againstskewingwhen'its outer end is being )gent aroundthe die head 32 and inorder to reinforce the arnu 27 when in the position shown in Figs. 2 and3, a 'lug 37 is cast or otherwise secured to the base for abutting 'en-`gagement with it. The arm 27 lmay be swung-.fout of. the way when largesizes of pi ,e are beingroperated upon.

' he construction of the die head is shown lnre clearly.in-Figsl.`5 6and 7, from which it will be noted that it is of substantially course,of greater length than the surface 38,

since the larger the pipe the greater must be the radius of curvatureofV a bend madetherein. The arm 31 o f thediememberisradapted .to bedisposed in the opening provided between the leg or arm 19, the jaw 5and the extension=15 and tobe secured against movement in the directionof its length by an arc- -ii'at-e lug formed integral therewith andadapted to slide laterally of the vise in an 'areuatel groove 43 formedin the top of the extension 15,.l Y Shouldithe pivots 25 and 29becomesomewhat worn or loose, the lug 4t2 engaging' in thek groove 43will hold the die and memberv against` displacement.

In Fig. l13 I have illustrated geoinetrically the formation of the dieheadfrom which it will be noted that the inner curve 38 is generatedbythe circular movement of an are of acircle a at the end of the radiusZiff about the ,point c ina direction transverseto the plane of thecircle ofthe arc with the chord of thegarcdisposed farthest'from saidpoint 02, while the interiorsurface of one side wall of the channel, i.e., the vsurface 39 is generated by the like movement and disposition ofthe arc of a. circle w movino' at the end. ofy a radiusiy about apoint". a. Of course, is greater than a, y is greater than b and thepoints c and zl are adjacent one another on the same side of thesurfaces 38 and 39, that is, to the rear thereof, but are notcoincident. From this description. it is believed that the relationshipof the curves 38 and 39 of the die head may readily bel understood. Itwill benoted that the curved surfaces 38 and 39 are substantiallyseparatedat one end of the die head, but merge finally at the end of thedie headedjacent the box of the vise, thus forming' the channel sidewalls of two portions, an upper or exterior portion and a lower orinterior portion of different curvatures extending for substantially thefull length of the channel surface.

lt will thus be apparent that the die meinber is adapted to receive andbend pipes of different diameters when the pipe is held between the jawsand by the member 27, and the die member is secured in position betweenthe arm 19 ofthe frame and thebase of the vise. Since each size of pipewhen bent betweengthe points of tangency A and B, as shown in Fig. 3,utilizes a-greater length of pipe than the perpendicular-distance fromeither'point of tangency-A or B to the other, due allowance must be madewhen ai'm to said base,vso that saidihead may be swung into and out ofsaid position.

3. In combination with .a pipe vise having a pair of jaws one ofwhich ismovable for receiving and clampinga pipe betweenztliem, a pipe bendingattachment having ahead `adapted to be disposed adjacent the openingbetween said jaws at one side thereof,"and means on the other side ofsaid jaws pivotally mounting's'aid head so that said head may be swungfrom one side of` said jaws to the other.
